SUBSOIIi-LPLOW:

Specification of Letterslatcnt'. Patents-deem. 30, 1913; Application filed August 2, 1812. Serial No. 712,936.

To all whom z'tmay concern:

Be it known thatI, JAMES: ALLEN HUG ems, a citizen of the United-States, residing at Red Springs, in the county of Robeson and State of North Carolina, have invented certain new and useful Improvements in Subsoil-Plows; and I do declare the folloW- ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the arttowhich it appertains to make and use the same. V y V This. invention relates to plows,and more especially'to subsoilers; and the objectof the same'is-to producean improved; device for attaching the subsoil standard tothe main plow so as-to permit it to swing from side to side or tobe adjusted vertically;

A further object is to improve'the constructionof the main plow beam in=order to adapt it for main connection with this attachment.

- mentalb'eam is the frontiendof the sub- Further objects and advantages will appear from the. following specification and claims, taken-inconnection'with the accom panying drawings,.wherein t Figure 1 is a side elevation ofacompjlete plow-embodying my improvement, parts being broken away; Fig. 2 is a horizontal sect-ion on the line 22. of Fig. 1, omitting allparts of the main .plow but its beam. Fig.3 is avertical section ofFig, 1. Fig. 4 is an enlarged perspective detail of the inner end of the main beam and the supplemental. beam, and the olevisconnected thereto. 7 i I1 N onclaim will be made in this application forthe main plow beam 13. carryingqthe plow point P,.for the main handles'H forthe inclined braces I 7 connected to said handle and pivoted at 2 to the beamat B,-nor for the subsoil plow point S which of "course may; be of any approved construction as also canlthe main plow= point P. l i 1 When my attachment isapp-liedto aplo-w of substantially the -construction roughly; in dicatedin thedrawing's either at the time said plow. is built orlater, Ipreferably ems ploy a supplemental beamlbolted orotherwiseconnected to the main-beam B. Pive oted at v3 to thelower .end of this supple soiltongue said front end herein shown as consisting of a clevf ismember 4 hingedly connected as at 5 with-a second member 6, this member being. shown-in Fig. '3, as y consisting. of parallel-side barsspaced:- apart by between saidside' bars forward of the spaced at this time. anti-friction rollerswill-be set forth below.

of the sleeve l5so as 1 plates) 8 riveted as at 9 within thelr rear ends, and the latter may be turned upward, backward at an angle, or preferably downwardinto hookslO as shown-in Fig. 2. Between the bills" of saidhooks on a cross'bolt' 11 is mounted an anti-friction roller 12; and wear. plates 8 onanother cross bolt 13 is mounted asecond anti-friction roller 14, the support a for which is by preference a sleeve surrounding said bolt between the side bars of the member 6 so as to hold them properly The function of these "The carriage forming a part of my improved attachment consists of duplicate spaced and substantially upright members 20 of strap iron whose lower ends are connectedb'yv a cross bolt 21 on which is mountedthe shoe, hereinshown as a;wheel-22, and whose upper ends extend thence forward as at 23, and thence downward as at 24 to the cross bolt .13, upon which they are mounted inside the side bars or membersqG of the tongue and againstthe opposite ends to hold the front ends 24 properly spaced. 'S-uch ends are provided with parallel upright slots 25 for a purpose yet to appear. The upright members 20 are connected by any suitable means such as the rivets 26 with the rear ends of the members 6 of the tongue, and thus the carriageis rigidly connected with the rear end of the tongue at a slight obtuse angle thereto as best seen in Fig. 1, and is supported-by; the shoe or wheel 22within the furrow F which has just been formedby the main plow or upon the surface of the ground if the main plow P is being dragged over the same, while the tongue is drawn forward by its connection at 3 with theoffset or beam 1 and the. draft is communicated through the hinge 5 and members 6 to said carriage. l

' The subsoilplow standard to which the subsoil point S is attached in any suitable manner comprises an upright member 30 passing loosely between the wear plates 8 andbetween the adjacent edges of the two rollers 12 and 14:, and having its upper end turned forward as at 31 and projected between the two downturned front ends-2A; of the members of the carriage as seen in Fig. 3. Heresaid frontend carries a cross bolt 32 which extends through the guideslots 25,

lever 36, which latter in turn is pivotally mounted as at 37 to the upper rear corner of the carriage. The numeral 38 designates a toothed segment supported y said riage, and 39 is a spring latch engaging this segment. and mounted upon the hand lever 36 and operated by'a thumb lever 40 in the usual manner. a

V WVith this construction of parts, when the hand lever 36 is thrown forward as seen in Fig. l the links 33 move the cross bolt 32 downward within the guide slots 25, and the entire subsoil standard with its point S is depressed, the upright member of the standard moving downward between the anti-friction rollers 12 and 14 and the wear plates 8 in a manner which will be clear. Thereafter forward movement of the main plow P cuts the furrow F, while the subsoil plow S cuts still deeper into the earth as indicated in this view. When now the depth to which the subsoil plow S will cut is to be adjusted, the operator manipulates the thumb lever to disengage the latch 39 from the toothed segment 38, and then swings the hand lever 36 so that the twin links 33 adjust the position of the standard and the subsoil plow point as desired. When subsoiling is not to be done,

the hand lever 36 can be thrown so far to the rear that the point S will rise above the bottom of the furrow F. When the entire plow is to be drawn over the surface of the earth, the subsoiler will be adjusted to such osition that its point S will be above the bottom of the main point P, and this position of parts will ordinarily be assumed at the end of the furrow or when the plow is turned around quickly. In this action the tongue members 6 will swing to one side as the upright hinge 5 permits, and in order that the entire attachment may not interfere with the main handles H, I preferably make use of a bail which may well be a piece of stout wire or metal rod 50 connected at its extremities with said handles-H as at the points 51 where the inclined braces 1 connect with the handles, and its center 52 pass ing loosely under the upper ends 23 of the carriage members as indicated in Fig. 1. Without further illustration than contained in this view, it will be obvious that when 7 this detail is employed and the plow is turned suddenly about as at the end of a furrow, the side movement of the entire attachment will be permitted as the length of the bail allows, and yet the parts cannot get out of place but the attachment will trail behind the main plow and resume its proper position as soon as the operator has turned the machine around and progressed for a short distance along his new course. The bail comes ordinarily into active use however, when the handles H are raised abnormally high or swung to one side without disengaging the subsoil point 'by the hand lever 36; and then the bail actsas a safeguard. V V

I do not wish to be confined to the use of the bail, nor particularly to any of the details hereinbefore set forth, further than as embraced in the appendedclaims; and it p is obvious that the sizes, shapes, proportions and materials of parts can be-altered at will without departing from the spirit of the 'invention.
